"Rather than announce these results and move forward with development, the administration's budget office has kept the independent cost report under wraps. Instead, a wildly inflated set of NASA cost numbers was invented, based on an imaginary "acceleration" of SLS development. Under these contrived numbers, which were leaked in yesterday's Wall Street Journal, development costs were forecast to increase to $57 billion - nearly double the amount that NASA and Booz Allen Hamilton agreed would be needed in the independent cost assessment."
Reader note: "the "inflated" numbers these Senators are now complaining about in their release are THEIR numbers from the NASA Authorization Act - if you extended it through 2017 with inflation. It seems these Senators don't even recognize their own numbers."
